This has also happened to me. And I live in Spain, but the truth is that something wrong was going on in my computer. It's got a virus and this virus must report to his company. There comes the scam. I also hanged up the phone. It was too weird.
I just got a call from these guys at midnight waking up both my parents. An Indian guy answered sayin that my computer is at risk of being hacked since I have it on sleep mode. I could not understand him because of his thick accent and asked him to put someone else on. He then proceeded to put on another Indian man with a thick accent which was ridiculous. These people just call at late night and early morning to make it else be like it's an emergency but do not listen to anything they say.
I've been getting calls from "John Kendall" approx 4 or 5 times a day for the past week. I called my phone company and they said I couldn't block them. They wouldn't do anything about it. Tonight the Arab caller said some really crude things to my husband about what he wanted to do to me! My husband cussed him out and hung up. He called back 5 minutes later and didn't say anything. I'm calling the sheriff's dept tomorrow but doubt that they will do anything about it. Why aren't the police doing anything about these calls? I'm sure other people have reported them. This is crazy. Why are they allowed to continue to harass us?
